Your main issue is that your images are taking way to long to load…
And seeing how the image sizes are small for example a 113.3KB takes 3.65 seconds to load tells me that your hosting provider is garbage.
If you want to speed up this website get better hosting preferably dedicated wordpress hosting such as wpengine.
I have the same theme for my ecommerce website and i have 1 second load times.
